Abstract

A system and compositions including zotarolimus and paclitaxel are disclosed, as well as methods of delivery, wherein the drugs have effects that complement each other. Medical devices are disclosed which include supporting structures that include at least one pharmaceutically acceptable carrier or excipient, which carrier or excipient can include one or more therapeutic agents or substances, with the carrier including at least one coating on the surface thereof, and the coating associated with the therapeutic substances, such as, for example, drugs. Supporting structures for the medical devices that are suitable for use in this invention include, but are not limited to, coronary stents, peripheral stents, catheters, arterio-venous grafts, by-pass grafts, and drug delivery balloons used in the vasculature. These compositions and systems can be used in combination with other drugs, including anti-proliferative agents, anti-platelet agents, anti-inflammatory agents, anti-thrombotic agents, cytotoxic drugs, agents that inhibit cytokine or chemokine binding, cell de-differentiation inhibitors, anti-lipaedemic agents, matrix metalloproteinase inhibitors, cytostatic drugs, or combinations of these and other drugs.
